" Application April 19, 1946;'se -iaijivqreeasve '1 r 1o This present"invention 'relates toi'a' motorcycle 'and 'more particularly to itscombination with a side frame forcarrying -an additional" passengerastride the side frame substantiallyat the side of the motorcycle drive;l

"Heretofore, in oneembodim'ent of prior art motorcycles, the passengerwas seated in a carrying means, conventionally known as a sidecar,"--wh'ich was mounted and supported between the'rear wheel of themotorcycle and an added wheel parallel-"to "the motorcycle" rear-whee,thus placing the passenger'alongside the wheels in a somewhat *low,undershing positiom This conventional'arrangem'ent had certaindisadvantages. The rider was *seated in 'suc-h" manner'that he wasunable'to raise himself'in preparation to absorb the unavoidable shocks1 resulting from a rough road surface'ovenwhichj The present inventionon theother hand, pro

vides a frame to seat astride it anaddi'tional rider so "constructed'that f the "rider may brace himselfg'against such shocks substantiallyin the same manner as the'driver of the motorcycle isable tod'o,whichthepassenger in: the"con-"- ventional side car is'unable-tddo.

With the conventional "side car arrangement,

an additional passenger finds diflicul-tyin" mounting or dismountingfrom the car; In order to mount afast-"moving v'eliicle of' this kind,the prospective ---passen'ger must move sub'- stantia'lly at rightangles 'tothe car and not in the same direction of motorcycle movement;The same condition is also encountered when the passenger dismounts'*from the conventional motorcycle side car since the passengenmust thenirn'ove away "from "it at right angles: 'to "the motion of themotorcycle. 'In either -case, th'e' passenger is required to change thedirectionof his' movement from th at of parallel to the direction ofmovement =of5the motorcycle "(forward Ior scams. (emcee-20am i a movingiv'ehicle; the conventionalisi'de mart-is at adisadvantage; i l v i i"Il1e::present invention therefore contemplates the provision of astructure from which acpase senger may rapidly'and safely mountor-'di'smount the moving motorcycle with a motion parallel to themovement of the motorcycle. "By-3 such arrangement, the passenger canstep ofi:to'-

the rear and decelerate easily and safely while:

istillirunning in the original direction 'of*tra'.ve1

as the "vehicle moves away fromhim. .The disadvantages of'the side carare encountered in thetricycle :where the passenger r is carried betweenthe two rear wheels and faces toward the'rear of :the vehicle. With suchm chinesflth'e passenger icannot readily dismount from the vehicle sincehe faces in the opposite: direction-toits travel and therefore; in orderto properly balance 'himself "when dismounting, the passenger i must'tur n in" the forward direction! while the vehicle is moving, a'somewhat difil'cult feat to accomplish on the small"and slanting runningboard found in thattype of vehicle, which of coursedoesnothave'handlebars tobe grasped and so provide the necessary support] I The present"inventioncontemplates the pro; vision of a structure on wh'ichthepassenger is seated similar to the seatingfof the driverso' that thepassenger can the furnished knee pads if as well as a handle bar or ringgrip for usein vmounting, 'dismounting "and as 'a support whilebackward) to asidewise movement"'(at right angles to it).

Thus, when mounting the side"car 'th'e passenger must of necessityencounter it in' anaofi for militaryand' police jpurposes requiringrapid and safe mounting "and dismountingircma fast tof indtorcy'cles andside cars will'be had, namely,

riding. Thus; the passenger may ride the" motorcycle, mount it'ordismount from it as easily and as conveniently as the driver can and"withthe same comfort.

The present invention also contemplates the provision of relativelylengthy foot boards" (which may be considered vehicle running boards)for the passenger as "well as the driverf" 'thus enhancing for"both'theease and rapidity; with which the machine. may be mounted and:

-dismounted.

Referring now to the drawings and more particularl to Figs. 1 to 3, aconventional motorcycle ln has mounted on it a frame structure l2astride which a passenger may be carried on the seat l4 and which seatI4 is preferably in alignment with and parallel to the seat "5 on whichthe'motorcycle driver is carried.

The motorcycle has the usual conventional elements including the frontand rear wheels l8 and 20, with their accompanying mud guards 22 and 24,the tank 26, the light 28, motor 30, transmission 32, steering posts 34and 35, handle bars 36, etc. The seat I6 is supported at one end on thetank 26 and at the other end by means of the spring 38 to the inside andoutside downwardly inclined tubular elements 40 and 41 of: themotorcycle frame; the tank 126 being mounted on the substantiallhorizontal inside and outside tubular elements 42 'and 43 of-the frame.

Mounted on the tank 26 are provided the conventional knee pads44 and 45on each side of the tank which give riding comfort to the motorcycledrive!" ing him to brace himself when re quired; v

The motorcycle frame includes the horizontal elements 42 and 43 on whichthe tank saddle or support 46 is cradled and which saddle or support issecured to the steering post collar-48 and the downwardly inclinedtubular elements 40 and 4| which latter are bolted or riveted to thefork 56.. the rear mounted the footboards 58 andBll for the driver ofthe motorcycle. r

The lower horizontal members 54 and 56 con-- tinue into the uprightmembers 62 which at their ends are secured to the tank saddle or support4 thus completing the motorcycle frame.

*Inorder to form the cradle like frame 12 on which the passenger seat l4and foot'boards 66 v and 68 are mounted; I securethe tubular-elements-l0 and 12-to' the head lug or support 46 from-which theyextendoutwardly and are-bent rearwardly to permit adequate'and proper turningof the wheel I8 when steering the motorcycle.

which continue into the downwardly inclined elements 18 and Bil, whichlatter aresimilar to the.

elements 40 and 4! and are also bolted or riveted to yoke membersmounted on the axle 82 of the side frame wheel 84, which latter is alsosup-'v plied with a mudguard 86. v

Lower inside and outside horizontal tubular elements 88 and 90 aresimilarly bolted and riveted to the yoke members mounted on the axle 62and continue into the lower inside and outside members 89 and 9|extending toward and secured to the lower inside member 54, thuscompleting the passenger carrying side frame l2.

The front end of the passenger seat I4 is cradled between the uppertubular elements 14 and 16' and the rear end of this seat connected bythe spring 38 (for illustration see Fig. 6)'to the downwardly inclinedtubular elements and 80.

4 If desired for rigidity, the members 10 and 12 may be connected by therigid spacer arm 92.

In order to mount the footboards for the driver and the passengerrespectively on the motorcycle frame and the side frame 12, I mount onthe axle 52, the inclined inside and outside arms 94 and 96 to which aresecured the angle supports 98 and I00.

Intermediate the motorcycle frame on the lower inside horizontal member54. I mount the support N12 to which is secured the angle support i114and on the outside horizontal member and in the same manner the anglesupport I06. Toward the front end of the motorcycle on the insidehorizontal member 54, I mount the support N38 to which the angle supportI it is secured and on the-outside horizontal support member and in thesame manner the angle support H2.

Thus, the 'footboard 58 is rigidly carried on the angle supports 98, m4and H0. The other ends of these angle supports are mounted in the samemanner on the inside lower'tubular member'BB of'thepassenger side=frameI2 so that'the foot board 66 is likewise rigidlycarried on the sameangle supports. 7 v

The otherfoot-boa-rdfii) is rigidly mounted on the angle supports I00,H35 and -H2 which-are suspended from the outside yoke member and theoutside lower horizontal element 56 in the same manner.

Mounted on menti ll of the passengerframe l2 in a similar manner, -Iprovide angle supports H4, H6 and H8 on which the outside footboard 68for the passenger is rigidly carried.

The angle l M is carried by the arm I l5'mounted' on the axle 82', the"angle H6 by the support H1 and the angle H8 by the support H9, thelatter two supports fixedon the lower horizontal ele-' ment asillustrated in Fig. 6 relating to a modification of my invention.

In order :to further rigidly connect the frame l2 to-the motorcycle; Imount the member l2!) on the axles 52- and-82- respectively by means ofI the arms I22 andl24'andin order that it will not interfere with readydismounting, I bow the member I20 outwardly'from the axles to the backofthe machine. l

Secured to'thehorizontal tubular members 14 and 16 in frontof the seatl4, I mount, for the comfort ofthe passenger, the knee pads I26 and l28and in order that the passenger may suitably hold and support'himself onthe seat 14, the

ring or handle bar I30.

It will now be apparent that I have provided a passenger carrying frameon which a seat is mounted and on which the passenger may sit astride ofthe frame and the. seat with his legs on suitable foot boards and hishands grasping a handle bar in front of him so that he (the pas-"senger) may ride at theside of the motorcycle in the same manner thatthe driver does and in alignment with the driver to thus provide a wellbalancedmachine.-

My novel passenger side frame may be made particularly adaptable forpolice and military uses by eliminating the rigid bowed member I20 ofthe machine illustrated in Figs. 1 to 3 so that the passenger (who maybe a police officer or soldier) may easily step to the rear off theframe l2 as the motorcycle moves in the forward direction. Suchconstruction illustrated in Figs. 4

to 6, to whichreference is now made and in which I like elements bearlike reference characters, elimmates the probable necessity of stepping,overa the lower outside tubular elestrike campus member 121 lflraswthepassengeradismounts the side frame l2 merelyiby stepping to? theirear;

lthisiewamrsthe passenger: inwdismounting round with one fifootvtdlbei'fol-lowed byrtliexnext .foot-awh e facing in the same directionthat the motorcycle is moving. In this way, the dismounting -p assengeris able=to retain his baiance as the motorcycle moves away zfnomfhi-m--when he dismounts and readyr-toxrface zthe:im-;

pending eld .of..action.,

But-forthe' elimination of the bowed member I20, the motorcycleillustratedi in Figs. 4= toi 6 is subst antiaily-thesame asthat iilus'trated in' i igs.

fllhe frame upper-members ll and 16 may be connected by :thespacer arm136: in order. to. make the side frame more-rigid. The knee pad's ldt,a'rad I28- ma'y beslidably mourrt'edmn the members 14 and 16 so thatthey may be adjustably positioned forwardly or rearwardly for a betterfit.

Referring now to Fig. 7, I mount on the angle supports 98, 104 and H0between the footboards 58 and 66, the intermediate structure or boardI38, which serves as a platform or other structure for carrying anydesired articles, such as luggage or police or military equipmentoranything else to be transported by the motorcycle.

It will now be apparent that I have provided a passenger side framewhich is so constructed and arranged that an extra rider is able to sitastride it and the seat mounted on it so that he may always face towardthe front and is provided with both knee pads, a handle bar and footboards by means of which he is able to brace and support himself to'meet any unusual shocks encountered in driving.

It will be further apparent that I have provided a passenger side framethat will meetthe services to which it will be subjected by police andmilitary requirements.

While I have shown and. described certain specificexamples of myinvention, it will be understood that such examples are illustrative andare not given as limitations, since other modifications within thespirit and scope of the invention will be apparent to those skilled inthe art. Hence, I do not intend to limit myself thereto,
